taken from a child who had cowpox. The boy
( 35 )developed a slight infection. Later, Jenner inoculated
the boy with smallpox matter and discovered that no
disease developed. Jenner wrote a paper describing his
results, but the Royal Society of Physicians, who were
skeptical about his unconventional approach, rejected
( 40 )it. Jenner published his findings independently, and
his paper became a bestseller. Within a matter of
years, the new procedure known as vaccination was in
general use throughout Europe and the United States,
and the fight against smallpox was underway.
( 45 )It was not until 1966, however, that the World
Health Organization was able to find the resources to
launch a worldwide campaign to wipe out the disease
altogether. In an immense project involving thousands
of health workers, WHO teams moved from country to
( 50 )country, locating every case of active smallpox and
vaccinating all potential contacts. In 1977, the last
active case of smallpox was found and eliminated.
Since there are no animal carriers of smallpox, the
WHO was able to declare in 1980 that the dreaded
( 55 )killer had been conquered. For the first time in the
history of medicine, a disease had been completely
destroyed.
